Application filed November 14, 1813. Serial No. 801,044.

To all 'u1/iam t may concern.'

Beit known that I, JOHN FRAME, a citizen of the United States, residing at Searsport, in the county of lllaldo and State of Maine, have invented certain new and useful Improvementsin Mixers, of which the following is a specification.

My invention relates to mixers,

The primary object of my invention resides in the provision of an improved agitating means for a mixing device for etliciently beating eggs, mixing drinks or performing like functions, said agitating means embodying preferably two rotating elements, one rotatable in one direction to lift the material from the bottom of the vessel in which it is disposed and conveying it upwardly, the portion of the material being acted upon being thrown laterally therefrom due to the centrifugal force where it is again .agitated by the other element which simultaneously7 rotates in an opposite direction, the remaining material which is carried toward the upper end being deflected through the medium of efficient means and thus directed toward the bottom of the receptacle to be subsequently acted upon for efficiently mixing materials.

A further object of my invention is to provide an improved means for holding the device in stationary position while the same is being operated.

A still further object of my invention is to provide a device that is simple in construction, eiiicient in operation, and one that can be manufactured and put upon the market at a minimum cost.

Other objects as well as the nature, characteristic features and scope of my invention will 'be clear from the following description taken inconnection with the accompanying drawingand appended claims.

In the drawings: Figure 1, represents a side, elevtional view, partly in section of my invention. Fig. 2, represents a plan view of my invention taken on line 2 2 of Fig. 1. Fig. 3, represents a fragmentary, sectional view of my invention taken on line 3*?) of Fig. 1

Referring more particularly to the drawings, in which similar reference numerals designate like Y or corresponding parts throughout the different views, I provide a tubular shaft 1 on which is rigidly mounted a spiral agitator 2, comprising essentially 1n this instance a sleeve 8, provided with spiral blades 4, tapered toward their upper end. The shape of these blades 4vary for diderent work. For instance, if mixing cement or heavy material, the pitch ofthe blades would not be so sharp and the curve of the outer edges of the same would be more abrupt inwardly. When mixing lighter material for ordinary cooking, the pitch would be sharper and have less hook to the blades.

t Revolubly mounted above the spiral agitator 2, about the shaft 1, is a tubular sleeve 5, on the lower end of which is formed an annular collar 6. Formed integral with the `under surface of the collar is a disk like.v supporting flange 7, having openings 8, through which extend the upper ends of the ribs 9, of the substantially conical cage agitator 10, By this arrangement it is to be noted that the supporting flange 7 constitutes a deliector having a diameter wider than the narrow upper end of the blade,v so as to directs the material lifted up from the bottom of a vessel, not shown, by the blades, toward the bottom in order that the material may be subsequently acted upon by the enlarged end of the'blade. The cage agitator 10, which encompasses the spiral agitator consists essentially of downwardly depending ribs 9, formed of wire or the like material, the outer ends of which are preferably embedded as at 11, at spaced intervals in the periphery of the annular collar 6. The ribs are arra ged in spaced relation with the spiral agitator 2, and terminate in loops 12, at their lower ends which are engaged upon the annular brace 13, made of similar material,

its inne? end a bevel gom? which meshes with lie bevel gears 1.4 and. 21. in is zigidy seoure 'no the outer onli of Je shaft 23, which arm has; for 'lod om iis fre@ and a bandi@ 26.
